2001 Audi A6 Quattro Question: fresk water leaking into pass side floor

fresh water is coming from behind glove box and leaking onto pass side floor, not just a few drops, but guarts. i also hear water sloshing from behind dashboard. Is there a vent that be clogged and if so where is it? -
Answer 1
I had the same problem and it turned out that the vent in the engine compartment at the firewall, passenger side next to the ac filter was blocked. Cleared debris and haven't had an issue since -
Answer 2
Also, you may want to check to windshield lower cowl. Mine had a crack in it which allowed water from windshield to flow underneath and then directly into fresh air box. It is approx. 89$ from dealer and easy to self install. -
